Greenworks 0.080" 160-Foot String Trimmer Line

What It Is

This is a Greenworks 0.080-inch diameter, 160-foot spool of replacement trimmer line for battery-powered and gas string trimmers. It’s designed for light to medium-duty trimming of grass and small weeds around lawns, gardens, and edges.

Fitment & Compatibility

• Line diameter: 0.080-inch (2.0mm). This fits most standard trimmer heads that accept line up to 0.080-inch. Do not use in heads rated for thicker line (e.g., 0.095-inch or 0.105-inch) as it may jam or break.
• Compatibility: Works with any trimmer using 0.080-inch line, including Greenworks models (e.g., 21012, 21112, 21212, 21312) and many other brands (Toro, Ryobi, Black+Decker, Craftsman, etc.). Check your trimmer’s manual or existing line spool for the exact diameter.
• OEM vs aftermarket: This is Greenworks OEM line, so it’s guaranteed to match their bump-feed or fixed-line heads. For other brands, confirm the head accepts 0.080-inch line and that the spool fits (most universal heads do, but some proprietary heads require specific spools).
• What to check before buying: Measure your current line diameter with a caliper or ruler (0.080-inch is slightly thicker than a paperclip). Also verify your trimmer head’s line capacity—this spool holds 160 feet, which is more than enough for most single-line heads.

Key Things to Know

• Quality: Greenworks line is a standard twisted nylon—durable for grass and small weeds, but not heavy-duty for thick brush or rocky areas. It will break faster on hard surfaces than thicker lines.
• Installation: Easy to reload into bump-feed heads—just cut a 20-30 foot length and wind evenly. Fixed-line heads require precise cutting to length (usually 8-12 inches per side). No tools needed.
• Gotcha: The 0.080-inch diameter is on the thinner side. If your trimmer is powerful (e.g., 40V+ or gas), you may get better performance with 0.095-inch line for heavier work. This line is best for smaller electric trimmers.
• Storage: Keep the spool in a dry place—nylon can become brittle after prolonged sun exposure or freezing temperatures.

Should You Buy It

Yes, if you own a lightweight electric or battery trimmer (especially Greenworks) and do routine grass trimming. It’s a reliable, affordable OEM option that loads easily and performs well on standard lawns. Skip it if you need thicker line for heavy weeds or rocky terrain—go with 0.095-inch or 0.105-inch line instead.
